Sorry, that is not possible. If you change the camera with higher resolution, you'll also need to replace the CPU and DSP with something fast enough to process increased data stream, not to mention a new firmware that is aware of new camera and has drivers for it. As you go through this process, you'll end up with a completely new drÐ¾ne, something like Bebop.

That YouTube video isn't much of a mod, but does provide some info on the matter. I ordered a 1/4 CMOS with a wide angle lens, but here's hoping it will fit. The idea is that there should be lenses for these type of small cameras that we can use.
